User manual GIANT BICYCLES ANTHEM SERVICE MANUAL

[. . . ] Damping: Internal mechanism to control the speed of compression or rebound. PSI: Pounds per square inch Rebound: The extension or return stroke of the shock. Topped Out: When shock or fork returns to its fully extended position rapidly and produces an audible "clunk". [. . . ] Typically, the heavier the rider [and higher the neccessary spring rate], the more rebound damping is required. Please refer to this guide for details on how to set rebound damping date. You should also refer to the individual shock manufacturer's technical manual for specific information. AIR SHOCK SET-UP Giant cross-country and trail bikes feature an air shock equipped Maestro suspension design. Pump the main air chamber to a psi (pounds per square inch) equivalent to rider's body weight . Push the rubber O-ring that is around the shock's shaft all the way against the base of shaft (closest to shock body). Position your bicycle next to a wall so that you can sit on the bike with both feet on the pedals while steadying yourself with one arm. Dismount gently and look at how far the O-ring has moved down the shaft. Refer to the Sag Recommenda-tion Guide below for proper sag measurements. Maestro Sag Recommendations: Anthem: 1/4" (6mm) O-ring movement SETTING AND ADJUSTING REBOUND DAMPING 1. If you are unfamiliar with rebound damping, perform this procedure: With full body weight, push down on the saddle forcefully to compress the shock. Next, turn the rebound damping knob clockwise until it stops and compress the shock under full body weight. Next, turn the damping knob counterclockwise a few turns and re-perform your compression testing until the shock rebounds just slightly more slowly than with no damping. To check the rebound damping rate while riding, ride off a curb while seated. The rear suspension should bounce only once upon rebound (the heavier the rider, the more damping will be required). If the suspension bounces more than once, turn the damping knob in the appropriate direction until one bounce is achieved. FRONT SUSPENSION TRAVEL & SAG GUIDE To determine bike's front suspension travel adjustments and recommended settings, please refer to the fork manufacturer's technical manual. A suspension fork is effective at both absorbing bump forces and helping the tire to track the ground for improved traction and braking control. When in active mode, a fork will rely on sag to keep the front tire in better contact with the ground during braking. AIR SPRUNG FORKS As a general guide, pump the main chamber (main spring) to a psi equal to 70% of your body weight. [. . . ] Use only low pressure water, or bucket water with a soft nylon bristle brush and mild dish soap to clean the frame and components. Always use LoctiteTM Primer (#7649) and LoctiteTM blue Removable Threadlock (#242) or similar material on thread of fixing bolts of calipers and rotors during re-assembly. Replacement of rear shock Shock mounting bolt Shock mounting bolt Steps 1: Loosen the shock mounting bolt and remove the shock. Repeat Step 1 in reverse to reassemble the rear shock. Recommended torque for the shock mounting bolt is 90-110 kgf-cm. Replacement of rocker arm Before dismantling the rocker arm: Remove the rear shock. Rock arm Rear Triangle Bolt Rock arm Bolt Step 1: Loosen the bolt and remove the rocker arm. Repeat Step 1 in reverse to reassemble the rocker arm. Recommended torque for the rear triangle bolt is 120-150 kgf-cm. Recommended torque for the shock mounting bolt is 90-110 kgf-cm. Replacement of Rear Triangle Before dismantling the rear triangle: Remove the rear wheel set. [. . . ]
